uncertainties and other factors that may cause the actual results, level of
activity, performance or achievements of Silver Wheaton to be materially
different from those expressed or implied by such forward-looking statements,
including but not limited to: fluctuations in the price of silver and gold;

exploration activities, economic and political risks of the jurisdictions in
which the mining operations are located and changes in project parameters as
plans continue to be refined; and differences in the interpretation or
application of tax laws and regulations; as well as those factors discussed

mining projects will be completed in accordance with their public statements
and achieve their stated production outcomes, and such other assumptions and
factors as set out herein. Although Silver Wheaton has attempted to identify
